Karen my wife is a descendant of the Henry Dillon that you are seeking information on.I don't have the specific information that you are looking for however, if you have not yet run across his family and descendants check at the following: http://freepages.history.rootsweb.ancestry.com/~harringtonfamilies/dillon.htmhttp://freepages.history.rootsweb.ancestry.com/~harringtonfamilies/dillon.htm
I think this info is ginned up by the genealogy folks in Monroe County. They might be able to find the info you need if you contact them. also there is an individual in Alex. Va. who keeps the info updated.
